everyone has different wants & needs, me want to keep the freezer at 2f and refrig at 34f, try that with the ammonia box. so went with he Samsung 24 cuft, two thermostats, frost free, use 4 8G8D Gells with a 2500 watt inverter and 100 amp smart charger.

BTW, I have a fire extinguisher with a automatic release head in my fridge compartment. It is sure nice to be able to switch the fridge from AC to propane as needs be. It makes dry camping much quieter.

If you're dry camping and running any type of electrical load, you're going to have to run the generator some time. The trick to this (and I stand on my soap box many times about this) is to make your generator as silent on the outside as possible. If you can just barely hear the genset standing 10ft away-that's about right. On my truck, my goal is to have it so quiet, it will sound maybe like an A/C running.

I only have propane for my stove and furnace. Everything else is electric-which I love the reliability of it all. Having big enough batteries to only run the genset during the day for a couple of hours is the key. Good Luck, TomC

TomC - I have to respectfully disagree - you can design an electrical system to not need a generator. I full-time in my MC-7 and have not used a generator over the last year (just recovered about 20cuft of space getting rid of it). Please keep in mind we follow the weather - Summer in WI and Winter in Yuma, AZ. We spend from October till May boon docking in Arizona (Snider Hill, ImperialDam) Nevada (snowbird mesa, boxcar cove and several areas on the north side of lake mead BLM's) Utah (blackrock petroglyphs) and all over in national forest area.

Here are the details of my system - Full disclosure.

Power coming inMy solar system is designed for full time use and we full-time with this setup and never Solar panels - 4x Canadian Solar 255watt panels (1020 watts in total) fixed mounted at 25 Deg - uniracCharge Controller - Outback Solar FlexMAX80 (80Amp MPPT)Inverter - Outback Power FX2012 (12V 2000watt duty rated - 5000watt max)Batteries - ~1200AH (12x 220AH 6V - wired out to 12V)

Real life numbersOn a good day (sunny) with the air conditioner running we will collect 6000 watts over the course of the dayOn a heavily overcast day we may only collect 800wattsOn average we collect 3700 watts (over the last 128 days of logging info on my system)The average is not representative of what we could collect if we used it. Keep in mind MPPT controllers only take what they need to get the batteries full. If the batteries are fully charged and the sun is up it may only take 100watts per hour (of the 1020 available) to float charge the batteries.

Power going out (this is every single electronic device tied to either AC (inverter) or DC and drawing on the solar/batteries.Lighting - DC - 37.8 watts max (all lights on) - we have normal light fixtures, wired to 12V DC and using 12V DC Screw in bulbs. (9 bulbs times 4.2 watts each = 37.8watts)Ventilation - DC - 28watts - one fantastic fan - I really need to put one in the bathroomAirConditioner - AC - 240/1008 watts (960watts x 5% loss at inverter) - 240 watt running the fan and 1008 with fan and condenser - so it alternates while it is on.Washer/Dryer - AC - 294watts (280watts x5% loss at inverter) - Splendide ventless This is wash cycle only as we don't use the drying feature (the line dry in AZ only takes about 15 minutes Water pump - DC - 60 to 95wattsJuicer - AC - max 300 watts - I don't have a reading on this oneBlender - AC max 1400 watts - I don't have a reading on this one eitherInverter - DC - 40watts - Many people do not realize in addition to the 5 - 10% loss to push power through the inverter they also have a load of their ownTelevision - AC - 48watts (5%loss…) Wireless Antnna/repeater - DC - 12watts - wilson wireless antenna to get cell signal where it is weakFreezer - DC - 170watts per day - haven't measured it yetMisc - AC - 600 watts per day average - Phone chargers, laptop chargers, battery charger for tools, outdoor led lights, Electric blanket - AC - 90 watts max - Rice cooker - AC - 430 watts - we run this thing at least every other day.

Note the hot water is provided by a solar hot water system and uses no additional electricity (we do have hot water)

Some of the tricks to making it work-Run high electricity things like the rice cooker and washer when the sun is up - since the DC system is a bus with the solar coming in and batteries connected it will not take nearly as much electricity from the batteries as it would when the sun is down.-you have to have a DC shunt based meter to actually know what you are using and getting. the meter on the controller, inverter and such are not an accurate measure of what you are using, you have to have a meter watching currant at specific DC shunts.-

I think Cliff explained it best - If you take it out you have to put it back in. So it is a basic math problem. If you use 2900 watts per day and can recover that plus a 6 to 10% overhead for charging you may be able to use solar. You also have to account for a few days without sunlight - depending on your location. We have gotten through 15 days without much sunlight. We are willing to adapt our lifestyle to make this many days, we didn't run the washer or use the rice cooker for example.

We seem to use between 1800 and 5800 averaging around 2900 (based on DC shunt measurements made before the freezer was added)

As you can see the roof is covered (about 30% with solar electric panels)

This plc shows the inverter, charge controller and all of the fuses, breakers, disconnects… and the old batteries - I will never buy AGM batteries again.

Again I mean absolutely no disrespect - especially to TomC (thanks again for reaching out to me while I was broke down in Nevada last year).

"People who say it cannot be done should not interrupt those who are doing it."-George Bernard Shaw

what you are doing is great. But it is only achievable because, in your own words: "you follow the weather".

In our circumstance, which is not unusual, we use the bus in all seasons and in all weather, mostly in northern latitudes.

For example, sitting in the bush at a dirt bike race for 3 days in September in rainy weather, there is no amount of solar panels that will keep up to the electric needs of 3 or 4 guys. The generator runs for several hours a day.That is a fact of life.

We have solar panels on the bus. They are great in June and July, in clear weather, if we are not parked in the shade of a tree.

Dave, yeah! It sounds like you and I are on the same page. I recently bought eight 255W Sharp panels, and I plan on using two Morningstar 60A MPPT controllers to charge eight golfcart or L16 batteries. I'll also have some solar water heating panels, probably home-made, but with 2,040W of PV panels I may also be able to heat water with my water heater's 1,500W electric element after the batteries are 100% charged. I see that your panels are 96-cell, so I guess they're 48V? Mine are 60-cell panels that produce 30V, but I should still be able to put up to 120A into the batteries in order to get them charged up as quickly as possible. Each bank of four PV panels will be hinged to the central walkway to allow them to sit at anything from 20 degrees below to 50 degrees above horizontal. With this many panels almost my entire roof will be shaded, and this should help keep it cooler inside.

If you have the luxury of following the weather, then yes you can get by without a generator. I live in L.A. and am still working which means in summer, you're driving in 100+ degree weather to get anywhere. I only have roof top A/C's which means running the genset going down the road. I have seen numerous generator less conversions, but all are retired and follow the weather. Maybe when I retire I'll try without a genset. Good Luck, TomC
